OfficeJet 5610v - Hewlett Packard

This is a discussion on OfficeJet 5610v - Hewlett Packard ; I am trying to find a Transparent Materials Adapter (TMA) the 5600 series to
scan 35mm slides. The user manual refers to one, but I have been googling
for an hour now and can't find a match anywhere.
Any ideas?
